- Nehmo ? A better question would be, "Is there any reason I should use copper for inside water plumbing?" These guys
My suggestions: Use PEX, and don't rely on the plumbing contractor's advice. A lot of them aren't up on what's happening. There's more than one brand of PEX (cross-linked polyethylene), so choose. There are many other design considerations beyond material selection. For example, is a manifold system the way to go?
Supply more details about your planned house: size, location, heating & cooling system, etc.
